Specification of Letters Patent.

Patented June 1, 1915.

Application filed December 8, 1913. Serial No. 805,216.

To all whom it may concern C Be it known that I, CHARLES V. MoIN- at Indianapolis, county of Marion, and State of Indiana, have invented new and useful Improvements in Operating Devices for Coke-Oven Doors, of which the following is a specification.

This invention relates to novel means for operating the doors of coke ovens by which each door is maintained at all times in parallelism with its frame, while furthermore any undue friction and jamming between said door and frame is avoided, so that the frame is relieved from undue strain and the operation of opening or closing the door is facilitated.

In the accompanying drawing: Figure 1 is a side elevation of a door operating mechanism embodying my invention, part of the oven being shown in section; Fig. 2 a front elevation of the door operating mechanism proper", and Fig. 3 a sectional plan of Fig. 1.

My improved door operating mechanism comprises a car or other support 10 adapted to travel in front of a tier of coking chamber 11 provided in a coke oven 12. Each chamber 11 has at its moutha stationary door frame 13 adapted to be engaged by a door A for closing said chamber. The door is shown to be composed of an inner casting 14 lined with fire proof bricks 15 and faced with a steel plate 16. Casting 14 is provided with depending lugs 17 supporting a transverse axle 18 that carries a roller 19. The latter engages the lower rail 20 of frame 13 and thus supports the weight of the entire door when fitted in position. To

the plate 16 of the inner door section is bolted the steel plate 21 of an outer door section, said plate 21 projecting beyond plate 16. To the outer edges of plate 21 is secured a rearwardly opening channel 22 packed with asbestos or other insulating material 23. When the door is closed, packing 23 engages a continuous pipe 24 fittedr around the door opening and secured to a suitable rest 25 bolted to frame 13, said pipe having preferably connections (not shown) for causing'a suitable cooling medium to pass therethrough.

For operating the door, means are provided that guide it in true parallelism with seition, while additional means serve to slightly raise or ease the door before the same is withdrawn from its frame. The means for holding the door and carrying it in parallelism with its frame, comprise essentially a hooked lever 26 adapted to engage the correspondingly shaped hook 27 of a bracket 28 bolted to plates 16, 21 as at 29 in proximity to the upper ends thereof. Near their lower end, there is bolted to plates 16, 21, an armor 30 that is adapted to be engaged by a plunger or abutment 31 which prevents the door fro swinging on hook 26.

Hook 26 as well as abutment 31 are movably mounted upon support 10 in the following manner: Support 10 is provided wlth a pair of spaced lower bearings 32 and wlth'a-pair of standards 33 having upper bearings 34 that are arranged in vertical alinement with bearings 32. Within each bearing 32 is rotatably supported an axle 35 to which is firmly secured the forked lower end 36 of a lever 37, said lever being provided with a forwardly extending arm 38. In similar manner, each bearing 34 is provided with a rotatable axle 39 to which the forked vertex 40 of an elbow lever 41, 42 is connected. The free ends of the laterally opposed lever arms 37 are furnished with bearings 43 that are mutually connected by a transverse shaft 44, while the lever arms 41 have bearings 45 connected by a transverse shaft 46 arranged vertically above shaft 44. Upon shafts 44, 46 are loosely mounted the hubs 47, 48 of a first connecting link or carrier 49. Arms 38, 42 are provided with bearings 50, 51 supporting respectively transverse shafts 52, 53 upon'which the hubs 54, 55 of a second connecting link 56 are loosely mounted. Link 49 has a pair of bearings 57 between which it is partly cutout as at 58. Within bearings 57 is loosely mounted an axle 59 carrying the door-supporting lever or book 26 hereinabove referred to. Link 49 is prolonged downwardly beyond shaft 44 to form a tail 60 that carries a cylinder or hub 61 the bore of which receives the stem 62 of abutment 31. The rear end of stem 62 is threaded as at 63 and passes through an eye 64 of tail 60 to which it may be clamped by nuts 65, so that the extent to which abutment 31 projects beyond hub 61 may be readily adjusted.

One.of the levers 37 is provided with a toothed sector 66 which is engaged by a worm 67 The shaft 68 of the latter is 1'0- provided with a toothed sector 73 engaged by a worm 74. The shaft 75 of the latter is journaled in bearings 76 of link 49 and is, by beveled gear 77, connected to a hand wheel 78.

The door maybe clamped to the frame 13 in any suitable manner, th e drawing showing it provided with a plurality of transversely extending lock bars 79, the laterally extending noses 80, of which are adapted to be engaged by manually operated clamp screws 81. These screws are tapped into links 82 fulcrumed at 83 to. brackets 84 of frame 13.

When 'it is desired to remove a coke oven door of the construction described, screws 81 are loosened and links 82 are swung sidewise. Hand wheel 78 is then operated to first raise hook 26 into enga ement with keeper 27 and then slightly ra1seor ease the door within frame 13, whereupon the electromotor 72 is started to turn sector 66 which motion is transmitted to arms 37, 38, 41, 42. In'this way, link 49 is moved toward the right (Fig. 1) to withdraw theeased door from frame 13. Finally support 10 together with the door is moved sidewise to clear the coking chamber.

It will be seen that by the cooperation of hook 26 and abutment 31.with the coke oven door, the latter is. positively held so as to always maintain a position that extends in true parallelism with the door frame, so

gage the door, a link carrying said hook that any edging or jamming'of the same during its insertion or withdrawal is effectively prevented. From Fig. 1it is apparent that in their original position, the shafts 44, 46 are located slightly back of shafts 35, 39 so that during the first stage of the removal of the door, the latteris slightly raised to avoid undue friction and prevent and oven armor.

It is obvious that the electromotor 72 may I. claim: 1 1. A device of the character described 'comprising a door frame, a door, an upper hook and a lower abutment adapted to en- 'an accidental loosening of the door frame departing from the spirit of my invention.

4. A device of. the character described comprising a door frame, a door, a carrier, an upper door-engaging member supported thereby, means for moving said member in a vertical direction independent of the carrier, a lower door-engaging member supported by the carrier, and pivotally mounted means for moving said carrier toward and away from the door-frame.
